JPS56126578A - Removing method of casting sand - Google Patents

Abstract

PURPOSE: To remarkably improve work environment, by roughly removing casting sand from a cast product before its temperature drops and improving its cooling effect.

CONSTITUTION: A cast product at high temperature after unpacking its casting frame is fed onto a vibrating conveyer main body 2 by a conveyer 1 with casting sand as left attached and firstly the casting sand on its upper half part is removed at a position immediately below a shot blast 4. Secondly, the cast product is inverted up-side-down when passing through a stepper part 3, and the casting sand from its lower half part is removed at a position immediately below the shot blast 4. Said cast product subjected to rough removal of the casting sand is fed to the subsequent processing step. The casting sand removed is dropped down together with shots onto a collecting plate 6, further dropped down onto the first separator 7 then the shot is separated from the casting sand, thus the casting sand is restricted to a rise of its temperature and cooled while passing through a conveyer 8 and the second separator 9.
